' CHARLES B. BUMSEY, or HOMER, new YORK.

WIRE-TWIST'IYNQ' 'roo SPECIFICATION forming part of Letters Patent No. 382,666, dated May 8, 1888. Application filed February 23, 1888. Serial No. 264,969. I (No model.) I

' comes necessary to join the ends of a broken.

wire or to connect a new supply of wire, and

these delays result'from the fact that the workmen are not provided with any proper tool or appliance for making the joints, they relying mostly upon their skill intwisting the parts of the wire together with their fingers. To remedy this difficulty, I have designed a tool by which wires can be easily and quickly united, and which will produce a joint both strong and inconspicuous.

. Referring to the accompanying drawing ""2 5 Figure 1 represents a perspective view of my improved tool; Fig. 2, a side elevation of the same; Fig. 3, a top plan view; Fig. 4, a seetional View taken on the line or a, Fig. 3; Fig. 5, a sectional view taken on the line '31 y, Fig. 3; Fig. 6, a perspective viewv of the twisterwheel detached. Figs. 7 and 8 represent views of a partially and fully completed joint, 'respectively, made by means of my improved tool. 5 5 Similar letters of reference in the several figures indicate the same parts. 7

I The letterA represents the handle of the instrument; B,a shank secured therein,and hearing at its extremity a head,O. Formed with or secured to this head in any suitable manner are plates D D, that are slotted at their upper ends, as shown at d, and provided with perforations d d, into which the said slots d lead.

E is a twister-wheel, having, preferably, a milled or roughened circumference, e, and cylindrical hubs or bearings e, which are journaled in the perforations d d of the plates D D,-as shown in Figs. 3 and 4:. The hubs or bearing portions 6" are bored out from opposite sides, so as to leave at the center of the circumference of the twister down through the hub portion 6', and'part way throughthe web or partition 6 to the center of the twister, 5 5 the said slot 6 in the twister being in line with the slots d in the plates D Dewhen the twister is turned to the proper point. Ipreferably make the entrances to the said slots 6 and dd flaring or V-shaped, inorder to facilit 6o tate the introduction of the wires to be united. Formed integral with and secured to the plates D D are arms d d whose upper portions are provided with slots at d also in line with the before-mentioned slots e and 1 din 6 a the twister and bearing-plates, respectively. These slotted arms 11 d serve to hold the wires to be united .in proper position while being twisted.

The way in which the tool is used in practice is as follows: The operator grasps the handle with one hand, and with his thumb appliedto the milled or'roughened circumference of the twister turnsthe latter until the'slots e, d d, and d" d coincide.- "He then with his other hand 7 5 .inserts in said slots the lapped ends of the wires to be united ,and while holding said wires with his thumb and finger down in the slots (1 in the arms rotates with thethumb of the hand holding the instrument the rotary twister five or six times, thereby causing a joint to be formed'similar to that shown in Fig. 7, which joint is fully completed by breaking off the. projecting ends w of the wire, (shown in said Fig.'7,) thus leaving the joint as represented 8 in Fig. 8. 1 By means of this little instrument wires can be united much quicker and neater than by the fingers alone, and the joints produced are not so noticeable in a woven fabric as are hand-made joints.

I do-not desire to be limited to any particular mode of constructing the parts'ot' thein strument', as there are various ways of making them that may be practiced. For instance, the rotary twister,insteadof being bored or out,

as described, may be cast or otherwise formed bearing-plates and in such relation to the latl0 ter that the wheel can be rotated by the thumb of the hand engaging the handle, substantially as described.
